Another object of the present invention is to provide a liquid coating applicator that is simple to handle, constantly ready to paint after loading, and which will fully and completely utilize all of the liquid material stored therewithin. w

Still another object of the present invention is to provide a liquid coating applicator ofthe type described that will automatically feed liquid coating material to the applicator for srnooth'and uniform coating of any desired surface.

An additional object of the present inventionis to of a conical plate 31.

provide a liquid coating applicator of the above type in which the paint stored therewithin is constantly mixed so as to further enhance the finished results attained thereby.

Still another object of the present inventionis tp provide a liquid coating applicator for applying various types of liquids to all types of surfaces that is extremely simple in construction, and which canbe manufactured in large quantities at relatively low cost.

All of the foregoing and still further objects and advantages of this invention will become apparent from a study of the following specification, taken in connection with the accompanying drawing, wherein:

Figure l is a perspective view, with parts broken away, of an applicator made in accordance with the present invention;

Figure la is an enlarged fragmentary perspective view of certain parts of the apparatus shown in Figure 1;

Figure 2 is a longitudinal cross sectional view taken along line 2--2 of Figure 1;

Figure 3 is a transverse cross sectional view taken along line 3-3 of Figure 2;

Figure 4 is a transverse cross sectional view taken along line 44 of Figure 2;

Figure 5 is an exploded perspective View of a drum forming a part of the present invention;

Figure 6 is an exploded perspective view of certain control elements forming another part of the present invention;

Figure 7 is a fragmentary exploded perspective view, in cross section, of certain parts of the apparatus shown in Figures 5 and 6 in assembled relationship; and

Figure 8 is a fragmentary plan view of certain control elements forming another part of the present invention.

Referring now to the drawing, and more particularly to Figure 1 thereof, a liquid coating applicator 10 made 2 in accordance with the present invention is shown to include a main U-shaped rod 12 that forms a supporting frame for the roller and is provided with a handle extension 13. The applicator or coating roller is supported upon one rod or leg of the U-shaped frame and includes a drum 16 which is provided with an undulated surface that defines alternating crests 17 and valleys 18. Equally spaced apart bores 19 extending through the valleys 18 of the drum provide communication with the interior of the drum which is completely closed by end walls 21 that are connected to the opposite ends of the cylindrical drum. These end walls 21 have radially extending projections 22 which fit into the undulating portions of the drum so as to provide a completely tight seal there- I longitudinally spaced apart bores 19.

Controielernents are provided for selectively sealing the bores 19 and opening them to allow a desired quantity of liquid material contained within the drum tov escape outwardly to be absorbedby a porous cover 33v which forms an exterior coating surface. In order to control this flow of fluid, the control elements, including bars 26 having equally spaced apart bores 27 are slidably supported w'ithinthe valleys 18 of the drum. One end of each of the bars 26 is provided with a flange 29 which are attached, by means of pins-or rivets 30 to a flange I It will :thus be recognized that axial longitudinal movement of the conical-plate 31'relativeto the drum 16 is operative to effect longitudinal sliding movement of the bars26 to move the associated bores 27 into and out of communication with the outlet bores 19 of the drum, thus controlling the outward flow of liquid: from the interior of the drum.- The drum 16 also includes an integral sleeve 23 that extends-longitudinally through the interior thereof and outwardly through both end walls 215.. This sleeve-slidably and rotatably receives, the supporting rod 47 of the U-shaped base and slidably supports the conical plate 31 thereon for reciprocating longitudinal movement, A compression spring 38 acting" between the conical plate 31 and an adjacent end wall, 21 of the drum normally urges these parts in opposite directions, movement in one direction being limited by the position of stop nuts 42 upon a longitudinally extending pin 40 which is slidably received through the conical plate 31 and is secured by means of an enlarged head 41 to the adjacent end wall 21 of the drum. By adjusting the position of the nuts 42, it is possible to control the extent of movement of the parts by the spring 38 so that in the stopped position, the outlet bores 19' of the drum are out of alignment with the spaced apart bores 27 in each of the bars 26, thus normally preventing the escape of the liquid from the interior of the drum.

The rod 47 includes a radially outwardly extending cam pin 44 which is slidably received within a segmental spiral slot 45 in a collar 46 that is longitudinally and rotatably displaceable upon the rod 47. A washer 48 interposed between the collar 46 and the conical plate 31 provides for relative rotational movement therebetween. An actuating handle type lever 50 hingedly supported upon the handle extension 13 of the base frame by means of a pivot pin 51 is operative to control the movement of the collar 46. A flexible cable 52 extending through a sheath 54 which is clamped to the base frame by means of spaced apart guides 55, is connected at opposite ends to a mid section of the handle 50 and theouter end of a radially extending arm 56 which is atented Dec. .15, 1959 integral with the collar 46. Thus, by depressing the handle 5d, the pull upon the cable 52 is operative to cause partial rotation of the collar-46, thus efiecting longitudinal movement thereof slightly along the length of the rod 47 by the combined action of the cam pin 44 and follower slot 55. This longitudinal movement of the collar 46 eifects longitudinal movement of the bars 26 which are connected to the conical plate 41, a predetermined distance to enable the bores 27 of the bars to move into alignment with the outlet bores 19 of the drum, thus allowing a quantity of fiuid to escape outwardly into contact with the porous cover 33. It will be noted that this cover is removably carried upon the assembled drum and control bars by means of elastic bands 34 at the opposite ends thereof. Similarly, the entire roller assembly is maintained in assembly with the supporting rod 47 by means of a lock nut 53 and washer 59.

In-actual use, the interior of the drum is filled with liquid of any desired type through the access open ng 24. Thus, as the liquid is applied to the surface, additional liquid may be admitted into contact with the porous cover 33 for actuating the control handle 50 so that the roller is constantly supplied with the coating fiud, thus saving time, and allowing for a uniform application of the coating material. Since-the drum is constantly rotating, the liquid contained therewithin is being mixed constantly, so that there are no streaks or differences of any kind between subsequent applications of the material.

While this invention has been described with particular reference to the construction shown in the drawing, it is to be understood that such is not to be construed as imparting limitations upon the invention, which is best defined by the claims appended hereto.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:
